Unmetric, a social media benchmarking company, tracked the social media campaigns of several top fast food restaurants, such as Taco Bell, Subway, Burger King, Dunkin’ Donuts, and Pizza Hut. The company compared them based on their Unmetric Score (as the company explains: “a scientific blend of 24 qualitative and quantitative social media metrics, weighted and balanced to produce a single benchmarkable number”).
